Abstract
The utility model provides a kind of separable structure of resistance twist bottom roll end part combination of four-roller compact spinning device, it can overcome the shortcomings of shaft coupling drive form in the prior art, have the characteristics that significantly increase resistance twist bottom roll end coupling structure driving torque load, increase coupling structure wearability and replace coupling structure convenient for low cost.
Description
Technical field
The utility model is related to the compact spinning apparatus on a kind of spinning machine, especially negative pressure gas flow formula four-roller compact spinnings to fill
The end part combination coupling structure for the resistance twist bottom roll set.
Background technology
In the prior art, the twisting resistance roller transmission of negative pressure gas flow formula four-roller compact spinning device, substantially there are four types of form,
Middle shaft coupling drive form is disclosed by Chinese patent application 2016200963009, and comparatively speaking shaft coupling driving is four kinds of transmission sides
One kind that structure is simpler in formula, cost is relatively low, transmission is more steady, but the knot of this resistance twist bottom roll and shaft coupling part integrated design
Structure, because structure space position is limited, resistance twist bottom roll end diameter is supported the limitation of axle journal at bearing for shaft coupling part, because
The width for being used as transmitting the male tenon structure of torque for resistance twist bottom roll both ends depends on bearing bore diameter, and relatively narrow male tenon width
Both the size of driving torque had been influenced, the wearability of tenon portion structure is also influenced.
Invention content
The purpose of this utility model is to provide a kind of resistance twist bottom roll and joins with the separable end part combination in both ends shaft coupling part
Axle construction can overcome the shortcomings of shaft coupling drive form in the prior art, have and increase coupling structure driving torque, increase connection
Axle construction wearability and convenient for low cost replace coupling structure the features such as.
The realization method of the utility model is：
The end part combination structure of resistance twist bottom roll, including resistance twist bottom roll, roller connector, bearing support and shaft coupling,
It is characterized in that resistance twist bottom roll both ends are equipped with threaded interior hole, roller connector one end is equipped with and gathers the cooperation of bottom roll threaded interior hole
External screw thread and guide post, roller connector middle part are equipped with the bearing guard of installation bearing support, and the other end of roller connector is equipped with shaft coupling public affairs
Tenon, shaft coupling male tenon coordinate with shaft coupling, and shaft coupling is equipped with the female tenon of both ends right-angled intersection.
Using the technical solution of the utility model, the coupling structure of resistance twist bottom roll can be made more reasonable, stress surface increase makes
Driving torque bigger, wearability is more preferable, and low cost when also allowing for coupling structure abrasion is replaced.
Description of the drawings
Fig. 1 is prior art resistance twist bottom roll shaft coupling driving structure schematic diagram.
Fig. 2 is the end part combination coupling structure stereoscopic schematic diagram of the utility model embodiment resistance twist bottom roll.
Fig. 3 is the end part combination coupling structure schematic elevation view of the utility model embodiment resistance twist bottom roll.
Specific implementation mode
Fig. 1 is prior art resistance twist bottom roll shaft coupling driving structure, and shaft coupling part is because structure space position is limited, resistance twist
Bottom roll end diameter is supported the limitation of axle journal at bearing, because resistance twist bottom roll both ends are used as transmitting the male tenon of torque
The width of structure depends on bearing bore diameter, and relatively narrow male tenon width had both influenced the size of driving torque, also influences tenon portion structure
Wearability.
Fig. 2~3 be the utility model resistance twist bottom roll end part combination coupling structure, by resistance twist bottom roll 1, roller connector 4,
A gaskets 5, bearing support 7, B gaskets 9 and shaft coupling 12 are constituted, and 1 both ends of resistance twist bottom roll are equipped with resistance twist bottom roll threaded interior hole 2
With guide hole 3,4 one end of roller connector is equipped with the external screw thread that coordinates with resistance twist bottom roll threaded interior hole 2 and guide post 6, in roller connector 4
Portion is equipped with bearing guard 8, and for installing bearing support 7 and B gaskets 9, the other end of roller connector is equipped with shaft coupling male tenon 10, and shaft coupling is public
The shaft coupling female tenon 11 that tenon 10 is equipped with both ends right-angled intersection with shaft coupling 12 coordinates.
The width of roller connector shaft coupling male tenon 10 is 18-25mm, thickness 5-8mm.Preferable width is 22mm, and thickness is
6mm。
Using the technical solution of the utility model, the end part combination coupling structure of resistance twist bottom roll can be made more reasonable, stress
Face increase makes driving torque load bigger, and wearability is more preferable, and low cost when also allowing for coupling structure abrasion is replaced.
